Most FSM software dashboards show you 30+ metrics. That's not useful -- it's noise. The businesses that actually improve their operations pick a small set of metrics that reflect the health of their business and track them consistently.
These 12 KPIs cover technician efficiency, customer quality, financial performance, and operational health. Each one includes a definition, calculation method, industry benchmark, and why it matters.
TL;DR
- The 12 KPIs below fall into four categories: efficiency, quality, financial, and operational health
- First-Call Resolution Rate and Technician Utilization are the two highest-leverage metrics for most field service businesses
- Track KPIs weekly, not just monthly -- problems that show up in monthly reviews are often 4 weeks old
- Benchmark data below is aggregated from industry research; your targets should be based on your own historical baseline first
- The best FSM software surfaces these automatically -- manual tracking in spreadsheets works but creates lag
Efficiency KPIs
1. Technician Utilization Rate
Definition: The percentage of a technician's available working hours spent on billable work (including travel to jobs).
Formula: (Billable hours ÷ Available working hours) × 100
Benchmark: 65-80% for most field service operations. Above 85% creates burnout risk and leaves no buffer for emergencies.
Why it matters: Utilization is the primary lever for revenue per technician. A technician at 55% utilization who moves to 70% adds roughly 1-1.5 billable hours per day without any new hiring. Across a team of 5, that's 5-7.5 hours of daily revenue recaptured.
2. Jobs Completed Per Technician Per Day
Definition: Total jobs completed divided by total technician-days worked.
Formula: Total jobs completed ÷ (Technicians × Working days in period)
Benchmark: 3-6 jobs/day for residential service; 1-3 for commercial/complex work.
Why it matters: Direct measure of scheduling efficiency. Improving this metric by even 0.5 jobs/tech/day has compounding revenue impact. Declining numbers often signal scheduling problems, technician performance issues, or excessive job complexity.
3. Average Response Time
Definition: Time from job request to technician arrival at the job site.
Formula: Sum of (arrival time − request time) ÷ total jobs
Benchmark: Under 4 hours for emergency/urgent service; same-day or next-day for routine work.
Why it matters: Response time is one of the top customer satisfaction drivers in field service. It also measures your scheduling efficiency -- businesses with optimized dispatch consistently outperform on response time without adding headcount.
4. Drive Time as Percentage of Work Time
Definition: Total technician drive time divided by total time on the clock.
Formula: (Total drive hours ÷ Total clock hours) × 100
Benchmark: Under 20% for efficient operations; above 30% indicates routing problems.
Why it matters: Drive time is cost without revenue. Route optimization that reduces this metric from 28% to 20% effectively adds 40 minutes of billable time per technician per day. For a 5-tech team, that's over 3 hours of recovered daily capacity.
Quality KPIs
5. First-Call Resolution Rate (FCR)
Definition: The percentage of service calls resolved completely during the first visit, with no callback required.
Formula: (Jobs resolved on first visit ÷ Total jobs completed) × 100
Benchmark: 75-85% is average; 90%+ is excellent.
Why it matters: Every callback costs you roughly 1.5x a normal job (full drive time + labor with no additional revenue). FCR is the single metric most correlated with both profitability and customer satisfaction. Low FCR usually points to parts availability issues, technician training gaps, or poor pre-job information.
6. Customer Satisfaction Score (CSAT)
Definition: Average rating from post-service surveys, typically on a 1-5 or 1-10 scale.
Formula: Average of all ratings received in the period (exclude non-responses from denominator)
Benchmark: 4.2+/5.0 or 85%+ positive for competitive positioning; below 3.8/5 indicates systemic problems.
Why it matters: CSAT predicts repeat business and referral rates. A 1-point increase in average rating is associated with 20-35% higher repeat booking rates in residential service. This metric also surfaces problems before they become reviews.
7. Net Promoter Score (NPS)
Definition: The percentage of customers who would actively recommend your business (promoters) minus those who would discourage others (detractors).
Formula: % Promoters (rated 9-10) − % Detractors (rated 0-6)
Benchmark: Above 30 is good; above 50 is excellent for field service.
Why it matters: NPS measures word-of-mouth potential. In residential service, referrals are typically the highest-converting lead source. Low NPS with an otherwise operational business often points to a communication failure -- customers who had acceptable service but weren't impressed enough to tell others.
Financial KPIs
8. Revenue Per Technician
Definition: Total revenue generated in a period divided by the number of active technicians.
Formula: Total revenue ÷ Number of active technicians
Benchmark: Varies widely by trade and market. Establish your own baseline and track trend.
Why it matters: This metric is the clearest way to assess whether your team is operating at full productive capacity. Declining revenue per technician while headcount is stable signals utilization or pricing problems. Increasing revenue per technician signals efficient scaling.
9. Average Job Value
Definition: Average revenue generated per completed job.
Formula: Total revenue ÷ Total jobs completed
Benchmark: Establish your own baseline; track trend over time.
Why it matters: Declining average job value can indicate scope creep (technicians completing jobs without recommending appropriate additional work), pricing inconsistency, or a shift in job mix toward lower-value work. Growing average job value often correlates with better pre-job qualification and technician-led recommendations.
10. Days Sales Outstanding (DSO)
Definition: The average number of days between job completion and invoice payment.
Formula: (Accounts receivable balance ÷ Total revenue) × Number of days in period
Benchmark: Under 15 days for businesses with in-field payment collection; under 30 days for invoice-based businesses.
Why it matters: DSO directly measures cash flow health. High DSO means you're financing your customers' operations with your own working capital. In-field payment collection via FSM software is the fastest single intervention to reduce DSO.
Operational Health KPIs
11. Schedule Adherence Rate
Definition: The percentage of jobs that start within an acceptable window of the scheduled time (typically ±30 minutes).
Formula: (Jobs started on time ÷ Total jobs scheduled) × 100
Benchmark: 85%+ is good; under 70% indicates scheduling or traffic/routing problems.
Why it matters: Late arrivals are the top driver of negative customer reviews in field service. Schedule adherence is also a leading indicator of the day's productivity -- a schedule that falls apart by 9 AM cascades into a lost day.
12. Technician Retention Rate
Definition: The percentage of technicians who remain employed at the end of a period (typically measured annually).
Formula: ((Technicians at end of period − New hires during period) ÷ Technicians at start of period) × 100
Benchmark: 80%+ annual retention is healthy for field service; below 70% creates significant recruiting and training cost.
Why it matters: Replacing a skilled technician costs $15,000-$30,000 in recruiting, onboarding, and productivity ramp-up time. High turnover is often a symptom of poor scheduling (overwork), poor communication, or compensation issues -- all of which FSM data can help surface.
How to Use These KPIs
Don't track all 12 at once. Pick 3-4 that address your current biggest pain points. Build a weekly reporting habit before expanding to the full set.

FAQ
How often should I review these KPIs? Weekly for operational metrics (utilization, jobs per day, schedule adherence) and monthly for financial metrics (DSO, revenue per tech, average job value). Daily dashboards exist in most FSM platforms, but daily variation is too noisy to act on -- weekly trends reveal patterns.
Which KPI has the highest impact on profitability? First-Call Resolution Rate (FCR) and Technician Utilization Rate consistently show the highest correlation with profitability improvements when improved. FCR directly reduces wasted labor cost; utilization directly increases revenue without adding headcount.
What if my current FSM software doesn't track these metrics? If your software cannot generate these reports natively, you can build most of them in a spreadsheet from exported data. But if you're regularly doing manual KPI work, it's a strong signal that you've outgrown your current platform. The time cost of manual reporting is often greater than the cost of upgrading.
